Well, per comments on and off list, it is evident that the model of Super Record post I was discussing does indeed have trouble with slipping. I seems to me that the cause of the problem is that the convex washer that presses against the bottom of the post is absolutely smooth and chromed to boot. Typical beautiful smooth Campy chroming, but in this case it actually contributes to the problem.

As I noted, the post in question is the one-bolt model with the exposed hex head bolt. I believe Campy later went to a one-bolt design with an allen head bolt. I believe I have at least one of the later allen head posts as well, and I don't recall this problem with the later design. Did the later design have a grooved surface on the convex washer, or at least not a chromed surface? It appears the solution for this post is to roughen the contact surface somehow. Some have reported inserting a bit of sandpaper or wire mesh under the convex washer. If one were willing to use nonreversible means, sanding off the chrome and perhaps filing some grooves at 90 deg angle to the curve would probably do the trick as well.

By the way I have a couple of Zeus 2000 one bolt posts. These used an allen head bolt and they never slip. I believe the bottom of the post and the concave washer have grooves or teeth on the Zeus post. It's no secret that I consider the Zeus 2000 gruppo clearly superior the the Campy Super Record gruppo. This is just another demonstration of that.
